Completed in November 2003 and operational in December 2003, the BESS is one of Golden Valley Electric Association (GVEA)\u2019s initiatives to improve the reliability of service to GVEA members. In the event of a generation- or transmission-related outage, it can provide 25 megawatts of power for 15 minutes or up to 40 megawatts (MW) for less time. Being able to produce 40 MW makes GVEA\u2019s BESS one of the most powerful battery energy storage systems in the world in terms of MW output. One of the requirements for construction of the Intertie was a reactive power supply capable of delivering power, 如果发电失败. As shown below, the BESS has been meeting those needs.<\/p>\n

BESS at Work for You<\/h2>\n

Here\u2019s how the BESS works: When GVEA brings power up the Intertie from Anchorage utilities and one of their generators loses power, some of our members experience an outage. The same happens if we lose one of our own generators. But with the BESS, we can cover 25 megawatts of power instantly. This gives GVEA time to start up local generation, resulting in fewer outages. In 2019, the BESS responded to 49 events, preventing approx. 每米252,300次停电.<\/p>\n
